    // The original callback is only called for a single updated field, but the
    // Field API then updates all fields of the entity. For an update, the Field
    // API first deletes the equivalent row in the database and then adds a new
    // row based on the information in $items here. If there are multiple
    // Fivestar fields on an entity, the one being updated is handled OK
    // ('rating' having already been set to the new value), but other Fivestar
    // fields are set to NULL as 'rating' isn't set - not what an update would
    // be expected to do. So set 'rating' for all of the Fivestar fields from
    // the existing user data in $items. This preserves the user vote thru Field
    // API's delete/re-insert process.
